CHECK-ROW WIRE.

SPECIFICATION forming part of Letters Patent No. 469,403, dated February23, 1892. Application filed July 18, 1891. Serial No. 399,908. (Model)T0 at whom it may concern:

Be it known that I, GEORGE D. HAWORTH, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Check-Row Wire, ofwhich the following is a specification.

My invention relates to check-row wire of the kind inwhich the cord orwire comprises a series of lengths or sections connected together bystops or buttons, so as to provide in effect a practically-continuouscord or jointed wire equipped with a series of stops or buttons arrangedat intervals with reference to the desired actions of seed-dropping orseedplanting machines.

The more prominentobjects of my invention are to provide a simple,economical, dur'able, and efficient construction of stop or button whichcan be cast in a simple twopart flask Without cores, and therebyrendered a practical commercial success on account of the simplicity andeconomy involved in its production; to provide a construction of stop orbutton involving theforegoing and adapted, when connected with the wiresections, to provide a desirable jointin the wire; to connectthe wiresections by stops or buttons which permit said sections to be broughtalongside one another, and thereby provide in effect a construction ofcheck-row wire which can be contracted and brought within a smallcompass for shipping purposes and for convenience in handling andextended when brought into service, and to provide certain novel andimproved details serving to generally increase the practicability andgeneral utility of check-row wire.

In the accompanying drawings, Figure 1 represents in perspective acouple of wire sections connected together by a stop or button inaccordance with my invention. Fig. 2 represents the said two wiresections similarly connected together with the stop or buttonillustrated in longitudinal central section. Fig. 3 represents the wiresections brought alongside one another for purposes of transportation.

In Letters Patent of the United States No. 208,814 and No. 236,025,heretofore granted to me, I have set forth a two-part or divided buttoncomprising a couple of hooks, each of which has its shank portion orbase enlarged and adapted to provide an eye for the end of a section ofthe wire, the check-row wire being made continuous bylinking the hookstogether.

In carrying out my present invention I form the stop or button A in onepiece, and while said button could be struck up I prefer, as a matter offurther and decided improve ment, to form it by casting, as hereinaftermore fully set forth.

The button A comprises a middle or body portion at, having a couple ofoppositely-arranged end lugs or end portions a, each adapted to providea double-beveled eye or opening c that is to say, an eye or openinghaving its annular wallformed with a double bevel, so as to slope orbevel off both ways from the middle line of such wall. The end portionsa of the button are in the nature of fiat perforated lugs or rings,which may be said to be laterally arranged and positioned in parallelplanes. These said end portions are connected together by thediagonally-arranged middle or body portion 66 of the button.

The wire sections B are threaded through the eyes at the ends of thebutton and are provided with suitably-enlarged ends 11, which abutagainst the inner sides of the end portions of the button when thecheck-row wire is in service, and hence serve-to preserve connectionbetween the Wire sections and the button. WVhile the ends of the wiresections can be enlarged in any suitable way, a preferred and simplemode of attaining such end is to bend the same into loops, as shown, itbeing observed that each loop is proximately fan or dovetail shape, sothat while the bent-back portion of the wire extends within the eye, thewire portions forming the the loopdivergc from one another back of theeye to an eX tent to prevent the loop from being pulled through the saideye of the stop. The stop can, however, readily turn upon the wires thusconnected with it, or the wires can readily turn in the stop, since thebeveled rear or inner side portion of the wall of each eye is inengagement with the two rounded-wire portions, and hence the wire willnot catch or take an undesirable bight or grip upon the stop.

. ience in transportation the wire sections can be pushed back throughtheir respectivelyallotted eyes, so as to bring them, for example, intothe relative position illustrated in Fig. 3, it being observed that inmy present construction the body or middle portion of the stop or buttonis so formed and arranged with relation to the eyes that it will notinterfere with theforegoing-described.manipulation of the severalsections of which the check-row wire is composed. It will also be seenthat the button in Fig. 3 can be moved alongthe wire sections ineitherdirection, and also that said tWo sections can be drawn,respectively, in opposite directions and independently of the stop orbutton until the arrestment of their movements by the abutment of theirenlarged ends against the shoulders or ab utments formed by thelaterally-arran ged end portions of stop or button. It may also be notedthat owing to the peculiar relative arrangements of the body and eyesthe wire sections when brought together, as in Fig. 3, can lie parallelwith one another, the stop or button in such case assuming substantiallythe position shown.

With regard to the beveled eyes or openings a however, no limitation isherein placed upon the particular form of body portion which can be usedin connection with such eyes, so long as the body portion is of a shapewhich will permit the stop to be cast in a simple two-part flask withoutcores.

As explanatory of the foregoing, it may be observed that the stop can becast in an ob lique or inclined position in the mold, the under side orhalf of the stop, including the lower half of each eye, being in thedrag, while the upper side or half of the stop, including the remainingportions of the eyes, will be in the cope.

It will be understood that in thus molding the stop the parting-line inthe sand will follow the general configuration of the stop.

A casual inspection of stops, such as proposed in United States LettersPatent Nos. 284,240 and 271,788, will enable those skilled in the art ofmolding to understand that the cordance with my invention, it canbe castin a two-part flask, since the two impressions, respectivelyrepresenting one and the other of the two halves of the stop, can bereadily made in the cope and drag, respectively.

The construction herein shown and comprising a couple of eyes, eachhaving a double bevel, is the preferred one, and compared with apossible construction involving eyes having each a single bevel is amatter of further improvement.

With reference to the foregoing mention of a single bevel it will beapparent that so far as the feature of the bent dovetail-shaped loopportion of the wire engaging in beveled portions of the eyes isconcerned the bevels at the inner sides of the end portions of the stopare alone of service; also-that by prolonging such bevels, so as toextend from the inner to the outer sides of such ends of the stop, thelatter could be cast as hereinbefore stated, and also the wires and stopcould be brought into the position shown in. Fig. 1.

What I claim as my invention is 1. A stop or button for check-row wire,formed in one piece and comprising a middle body portion havinglaterally-arranged end portions, each provided with a beveled eye,substantially as and for the purpose setforth.

2. A stop or button for checkrow wire, formed in one piece andcomprising a middle body portion having laterally-arranged end portions,each provided with a double-beveled eye, substantially as and for thepurpose set forth.

3. A stop or button for check-row wire, made complete in one piece withbeveled eyes at its ends, combined with wires having dovetailed-shapedloops arranged to engage in said beveled eyes, with the wire ends whichare bent back upon the wires extending through the eyes, so as to allowthe loop or diverging wire portions to engage the rear or inner bevelsof the beveled eyes, substantially as described.

1. A stop or button for checkrow wire, made in one piece and comprisingthe body portion a, having end portions'or lugs 0., adapted to provideeyes for the wire sections, said body portion being diagonally arrangedwith relation to the said eyes, substantially as set forth.
